Hello, I'm Chris. Thanks for seeking us for help.
Can you tell me what symptoms you also have?
Are you needing the diag steps for these codes?
You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
Thanks Chris

dash went blank, car starts in third gear and I have the aforementioned codes. No other problems before this occurred.
Expert:  Chris (aka-Moose) replied 2 years ago.
0073 is an ECM configuration error, which normally indicates the ECM is bad.
0503 is a VSS sensor reading incorrect.
0671 no such code.
0863 is a transmission control module communication issue.
I recommend trying to reprogram the ECM and TCM first before going into electrical diag.
